更新:低于1.4+的能力

使用LESS 1.4,不需要在逗号分隔参数的原始答案中使用的javascript.相反,在参数字符串末尾使用"虚拟"分号会导致逗号被视为列表分隔符,而不是参数分隔符,因此现在可以在输入多个转换时使用:

少于1.4+

mixin call(.transition-properties(border-top .25s linear, color .5s linear;);)中的分号非常重要.如果它被省略,则将删除两个参数之间的逗号,这将以无效的css规则结束.

.transition-properties(...) {
  -webkit-transition: @arguments;
  -moz-transition: @arguments;
  -o-transition: @arguments;
  transition: @arguments;
}


.yourClass {
  border-top: 1px solid black;
  .transition-properties(border-top .25s linear, color .5s linear;); /* semicolon is necessary */
}                                                                |
                                                          NOTE THIS SEMICOLON

.yourClass:hover {
  border-top: 6px solid #ff3300;

请注意,逗号位于两个属性值之间:

.yourClass {
  border-top: 1px solid black;
  -webkit-transition: border-top 0.25s linear, color 0.5s linear;
  -moz-transition: border-top 0.25s linear, color 0.5s linear;
  -o-transition: border-top 0.25s linear, color 0.5s linear;
  transition: border-top 0.25s linear, color 0.5s linear;
}
.yourClass:hover {
  border-top: 6px solid #ff3300;

原始答案[Pre LESS 1.4]

显然,细节取决于您的确切实施.但是,这一般说明了如何使用它:

.transition-properties(...) {
@props: ~`"@{arguments}".replace(/[\[\]]/g, '')`;
-webkit-transition: @props;
-moz-transition: @props;
-o-transition: @props;
transition: @props;
}


.yourClass {
  border-top: 1px solid black;
  .transition-properties(border-top .25s linear);
}

.yourClass:hover {
  border-top: 6px solid #ff3300;
}

如果您刚刚使用直线@arguments,最终没有逗号分隔:
